Strength and Security

Composite doors are made from a varity of materials, including uPVC, timber, insulating foam and glass reinforced plastic (GRP), these materials in combination with our industry leading, multi-chambered uPVC profile results in a very strong and secure entry door.

Composite door frames extruded by Liniar have a high resistance to weathering and don’t react to seasonal changes like a singular material door would.

The insulation foam core of a composite door provides a higher thermal resistance than timber doors, and are designed with an attractive woodgrain appearance (check with your composite door supplier or manufacturers’ warranties for details). While these doors may look like timber, because of the materials used to fabricate them, they won’t fade or discolour, warp in damp conditions or need painting.

Wide Range of Colours

Composite doors can usually be personalised to whatever colour scheme you’d like. It’s an easy way to give your home a punch of colour. Liniar door frames come in White, Cream, Rosewood, Light Oak and Irish Oak, as well as 7016 Woodgrain, Gale Grey Finesse, Black and Chartwell Green.

Composite door profiles from Liniar are available chamfered or sculptured and are compatible with 44mm and 48mm composite door slabs and boast a wide choice of finishes, hardware and glazing options.
